Sonerila heterostemon problems — and how to fix them
Sonerila heterostemon (Sonerila heterostemon) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Humidity crash
Leaves shrivel and drop when humidity falls. Maintain an enclosed, steadily humid environment rather than depending on occasional misting.
Cold shock leaf loss
A draft or a night below about 16°C causes sudden defoliation. Keep it warm and away from windows and doors in winter.
Leaf bleaching
Too much light flattens the silvery iridescence and burns the surface. Dial the light back to filtered or low-grow-light levels.
Rot from overwatering
The shallow roots and soft stems rot in waterlogged mix. Use an airy medium and let the surface just begin to dry before watering.
